Is going low carb dangerous?

At the initial patient visit, I try to learn about any special dietary restrictions my patients may have. A common diet is going “low carb” in an effort to lose weight. Emerging research, however, suggests that this could be dangerous when trying to conceive.

Folic acid is a vitamin that reduces the risk of having a child with a problem with it’s spinal cord, known as a neural tube defect. Folic acid is added to many common meals, like cereal, in order to fortify the food. Women who intentionally avoid carbohydrates, thereby consuming fewer fortified foods, may not have adequate dietary intake of folic acid.

This study found that women eating low carb had significantly lower dietary intake of folic acid. Women eating low carb were 30% more likely to have an infant with a severe neural tube defect such as anencephaly or spina bifida.

What you should do:

  • Talk to your doctor about any special diets you have before trying to conceive
  • Women should take a daily prenatal vitamin in addition to having a well-balanced diet while trying to conceive
